Explorers is the final, under 18 section, in the scouting family. Explorers range from 14-18yrs and usually draw members from multiple groups.
The Tervuren based Explorers need leaders - if you are aged 20-60 and enjoy working with teenagers, perhaps you could volunteer with them.
There is also Network aged 18-25 made up of a few ex group members. Please get in touch if you are a young adult and might be interested in joining.
